On Saturday,Grace Mugabe cranked up the pressure against Mnangagwa, calling him the “root cause of factionalism” that was gnawing at Zanu-PF, The Guardian report.

Until recently, Mnangagwa was tipped as Mugabe’s likely successor, partly because of his support within the country’s powerful security establishment and among veterans of Zimbabwe’s 1970s guerrilla war.

He was appointed vice-president in 2014, taking over from Joice Mujuru, who was axed after Grace Mugabe launched a campaign accusing her of plotting to topple the president.

Mnangagwa claims the long sitting president has been poisoned in August while away for treatment in South Africa. Report say’she was plotting to get Mugabe step down in his favour. Mnangagwa denies all allegations.

Emmerson Mnangagwa, 75, outing paves the perfect path for Grace Mugabe to become her husband’s successor.
